The documentation on :with could definitely use some work, IMHO ;-)  The 
good new is, all you need is

:with => ''boo''

This puts the value in params[:boo]

Adding the ''='' after ''boo'' tells Rails
you''re going to get fancy, which it
will certainly help you with if you want to do something like serialize all 
or some of the elements in a form to pass them back in a multi-level hash 
independent of the actual form submission.  It doesn''t sound like
that''s not
what you''re trying to do, though.

hth,
Bill

hi there sir and sorry to bother but it doesnt work
if I put some crazy in the :with I see an empty (--) debuging message

but if I use :with => ''boo'' nothing happens

this is what I have in my _form.rhtml

<%= collection_select ''address'',
''address'', @addresses, :id,
:address,{}, :onchange => remote_function(

                                 :update => ''shipping'',

                                 :url => { :action => :boota },

                                 :with => ''boo'') 
%></p>

in the controller
  def boota
    @pp = params[:boo]
    render(:partial => ''bo'' )
  end

and this is _bo.rhtml
<%= debug(@pp) %>

I dont really know what am I doing wrong but I cant make it work
thanks in advance

First, I''ll apologize in advance for my brief reply.  It''s
very late here
and I must sign-off quickly or risk wife-ly reprecussions. Hope you 
understand :-)

My recommendation / personal strategy in situations like this it simple. 
Make it simple.  By that I mean, generate a sandbox app with just the bare 
minimum of stuff in it to get the behavior you''re looking for working. 
For
starters, I''d get rid of the :onchange stuff.in the collection_select
and,
once I got that working, put an observe_field on it.  Then, and only then, 
would I try to combine them.

Again, sorry I can''t be more help tonight.  Time to retire.

Hope to hear back.

Best regards,
Bill

Sorry.  Just shows how very late it is here.  I just looked at my response, 
then the docs, and realized that collection_select doesn''t do what
you''re
trying to do.  Use collection_select to generate the select box and 
observe_field :with => ''boo'' to get the selection to your
controller method.

Be back in the AM.

Best regards,
Bill

thank you sir, it worked
but now I have a new problem
if the collection_select only has 1 item the observe field will not work
it works perfect with more than 1
thanks for all your help!
here is my new code:

<%= collection_select ''address'',
''address'', @addresses, :id, :address %></p>
<%= observe_field(
              :address_address,
              :update => ''shipping'',
              :url => { :action => :shi },
              :complete => "new
Effect.SlideDown(''shipping'')",
              :with => ''boo'')  %>
As I read that obseve_fields take the same arguments of link_to_remote
i have tried :on => click
focus
change
but no luck
if theer is only one item in the collection it wont work
